plese don't give me false answer.​

Answer 1

Answer:

please make me as Brainlist please

Step-by-step explanation:

a + b + C = 3 , a2 + b2 + c2 = 101

( a + b + c ) 2 = a + b2 + c2 + 2ab + 2bc + 2ca

9 = 101 + 2 ( ab + bc + ca )

( ab + bc + ca ) = - 46

a3 + b3 + c3 - 3abc (a+b+c)(a2 + b2 + c2- ab - bc - ac)

= (3)(101 + 46)

= 441

So, √a3 +b3 +c3 – 3abc = √441 = 21
